Yes, AH supports 8-way hats, in 2 ways.
1. Directly programmable in all 8 positions
The game has KP7 for front-left, KP9 for front-right, etc, so you can put these right on your stick.
2. Addable Views
For those with CH sticks, whose 8-way hats aren't directly programmable on the diagonals and are hardwired with the diagonals being the sum of the adjacent ordinals, you can get front-left with KP4 + KP8.
